pimpleDyMFoam -- lowered viscosity -- time step continuity errors getting large
I'm working on some cases with pimpleDyMFoam, which I have gotten to mesh and solve fairly well, but then when I go to drop nu from 1e-6 to 6.7e-7, I am getting time step continuity errors that go up into the 6000 range after a few seconds. This then sets my deltaT so low that the solution effectively halts. Any ideas why this would happen?
My guess would be something happening with either:
Are you using the same mesh for both viscosities? What kind of moving mesh are you using?
All the best,
